I just did 20 minutes of vigorous aerobic exercise per day for 8 weeks.
It was pretty good, I guess. My fitness is much improved. 150 minutes per week is what all the public health information websites recommend that everyone should get, so according to them I’m almost doing the bare minimum for the first time in my life. I’m pretty old, so it took some time for it to start having an effect. It feels like it will probably take another 8 weeks before my body actually starts getting used to it and stops getting stronger so quickly as it still is doing for now.
I’m on my fourth week of making a concerted effort to briskly walk at least three miles per day. Haven’t really changed my diet or my drinking habits, though, so it doesn’t feel like it’s doing much.
Baby steps! That’s the way to long term habit changes, you are doing great.
